Adopting Japanese ba3884bbe chip design, with treble and bass adjustment, enhance the definition of high and low bass, and enhance the dynamic effect. The adjustment of the potentiometer adopts the DC control method, and the separation of the potentiometer will not cause interference. It is convenient to use a single power supply.

Tweeter adjustment instructions:

The treble adjustment potentiometer has two functions: 1: when the potentiometer is adjusted to the far left (within the range of 3/1 clockwise), the BBE is straight-through (that is, the bbe function is turned off); 2: the potentiometer is adjusted clockwise after 3/1 The range is to turn on the bbe function, and the potentiometer is used for adjusting the treble at this time. In this way, there is no need to add a bbe switch. By adjusting the tweeter potentiometer, you can control the on and off of the bbe, which is more convenient to use and achieves two goals.
